Why RFID wristbands are more suitable for music festivals than NFC phones

RFID wristbands are featured in various modern festivals and events that simplify the way payment and sharing experiences go to social media.

Most RFID wristbands contain short-range (usually 3-5cm) passive RFID tags that don't require a battery, just get close to or tap the RFID reader to get energy. When the reader detects the RFID wristband, it automatically activates the magnetic field of the coil antenna inside the tag to supply energy to the tag, thereby transferring the data in the tag to the RFID reader.

Tags in RFID wristbands can be written directly to information or used as a key to access a personal security database.

There are many festivals around the world that use RFID wristbands to provide quick access, cashless payment and social media interaction for visitors. Users can choose to bind the RFID wristband to Facebook and Twitter accounts after purchasing tickets online, so that users can post, share or "like" favorite activities during the event.

RFID wristbands are used in several festivals in the UK in one summer, including the Isle of Wight Music Festival. It is estimated that at least 3.5 million visitors worldwide have used RFID wristbands so far.

Although NFC smartphones can be used as a substitute, the problem is that not everyone has an NFC phone, and an RFID wristband is available to everyone.

Another problem is that the phone needs to have its own power supply, and it may encounter the battery dead. There is usually no place to charge in the festival venue. If the phone is powered off, you can't use the e-wallet, e-ticket or social media on the phone.

But this is not to say that NFC has no use in festivals. Samsung Galaxy S4 is used as an RFID reader and is a good handheld scanner for small events.

The data shows that 3 million Facebook "likes" and one billion contactless transactions have been generated by RFID wristbands. RFID wristbands have been widely used.
